Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed February 15, 1912. Serial No. 677,735.

To all whom it may concern:

Be it known that I, Pn'rEnB. CRANE, of Long Lake, Hennepin county, Minnesota, have invented certain new and useful'Improvements in Tilling-lt lachines, of which the following is a specification. 7

My invention relates to tilling machines and particularly those employed for deep soil tilling. y I

The object of my invention is to provide a machine of strong, compact construction and which may be adapted for either surface or deep soil tilling.

A further object is to provide a machine in which the engagement of one disk or plow with a stone or obstruction will not affect the other disk.

My invention consists generally in a machine provided with a rear caster wheel and forward wheels on opposite sides of the ma;

chine frame-in staggered relation with one another.

Further the invention consists in independently supported diskplows arranged one in advance of the other. 7

Further the invention consists in means for adjusting one of the supporting wheels laterally with respect to the machine frame.

to adapt the machine for surface plowin In the accompanying drawing forming part of this specification, Figure-1 is a plan view of a machine embodying my invention, Fig.2 is a side elevation of the same, Fig. 3 is a front view illustrating the machineat work, Fig. 4 is a detail sectional view show-.

ing the adjustable connection of one of the wheels with the frame of the machlne, F 1g. 5 is a sectional view on the line a:m of

Fig. 4.

Inthe drawing, 2 represents the frame of has anaxle'? provided with a vertical por- ;t1on 8 fitting within a bearing 9 secured to therear end of'the bar 5 and adapted to rotate and slide vertically therein.

indicated in Fig. 1, and is adapted to run in the bottom of the furrow and bear against The caster wheel is incllned to the vertical, as

. theside wall thereof andguide the rear portion of the machine.

F or the purpose of raising or lowering the rear of the machine I provide a lever 9 plvotedon an arm 10 and having a link connection 11 with the axle 7. A quadrant 12 is mounted on the rear of the bar 5 and the lever 9 has the usual locking latch 13 for engaging the teeth of this quadrant and securing the at the desired elevation. v

plow is adapted to dig into the soil, its

depth ofcut being regulatedby the adjustment of the caster wheel and the operator of'the machine may increase or decrease this cut by the adjustment of the lever 9.

.Near the middle portion of the frame, preferably, I arrange one of the carrying wheels 15 having a vertical stud 16 slidable in a guide 17 secured on the frame and operatedby means of a lever 18 having a link connection 19 with said stud and adapted to move over a quadrant 20. The adjustment of this'lever operates to raise or lowerthe frame on that side of the-machine.

Pivotally connected with the I-bearn 3 and extending rearwardly therefrom 1s a Second draft bar or beam 21, having a bearing 22 at its rear end for a second disk 23. This disk operates in front of the disk 14- and in staggered relation thereto and operates to makeasecond cut in the furrow and a complete the deep soil tilling operation, as plainly shown in Fig. 3. The pivot of the drag bar 21 is vertically adjustable by means of the holes 2% provided in the bracket 25 to which the forward end of the drag bar is pivotally connected. To force this disk 23 into the soil, I prefer to provide a series of weights 26 carried by the rear end of the drag bar, the numberof weights being increased or diminished at will according to the pressure desired on 1 the disk. I also prefer tomount theorivers seat 27 on this drag bar so that the weight of the driver is utilized to force the deep soil disk into the ground.

To regulate the. depth of cutl provide a lever 28 having the usual locking latch to engage a quadrant 29 andv providedwith an" arm 30 having a flexible connection 31 with the drag bar 21. The adjustment of this lever 28 will determine the depth of cut of the disk 23. This construction allows the disks to work independently of one another. One disk may strike a stone or obstruction and rise to clear it without in any way affecting the other disk, and I am thus able to cut furrows more uniformly than usual in machines of this type.

A casting 32 is mounted to slide on the I- beam 3 and is secured thereto at intervals by bolts 33. This casting has a vertical socket in its, outer end to receive a sleeve 34; in which a stud 35 is vertically slidable. The lower end of this stud is outwardly turned and has a bearing for the hub of the carry- 7 ing wheel 36, which is also inclined to the vertical and adapted to bear on the bottom of the furrow and. resist the lateral pull of the machine when the disks are at work. A lever 36 is pivoted on the machine frame near the stud and has a locking latch to engage a quadrant 37 and a link connection 38 with the lower outwardly turned portion of said stud, the movement of said lever operating to raise or lower said stud and lift or depress the machine frame. The connection of the link 38 with the lower end of the stud 35 is near the hub of the wheel 36, as indicated in Fig. 3, and there is no obstruction on the vertical portion of the stud to prevent it from being drawn upwardly to a point where the lower end of said stud will be close to the frame of the machine, and the same is true of the adjustable connections for the wheel 15, as indicated plainly in Fig. 3. I thus provide for a wider range of adjustment than is usual in machines of this type.

Upon removing the bolts 33 from the 'I- beam, the casting 32 may be moved outwardly with the wheel 36 until the said wheel is at one side of the path of the plow disks and then by raising the disk 23 to the same level of the disk 14 the machine may be used for surface plowing, each disk cutting a furrow of the same depth.

I prefer also to'mount a lever 39 on the upper end of the sleeve 34 and projecting inwardly over the machine frame to enable the operator to-rotate the sleeve and the carrying wheel 36 to vary the direction of movement of said wheel with respect to the bottom of the'furroIw. The arm 39 is locked by means of a toothed bar 40 which is secured on the casting 32 and is slidable with it. Upon removing the bolts, the casting 32 may be adjusted outwardly to move the wheel 36 away from the machine frame so that it will nottravel directly in front of the disk 23, and adapt the machine for surfaceplowing. I

'In the operation of the machine, I may load the forward disk bythe weight of the driver or by the weights 26, or both, and.

force it into the soil to cut a'deep furrow,

the rear disk cutting a comparatively shallow furrow. Then on the next time around the land the forward disk will run in the furrow previously cut by the rear disk while the real-disk will be cutting another shallow furrow. In this way the forward disk cuts a deep furrow while the rear one is cutting a shallow furrow. If preferred, the forward disk and its beam may be raised to an inoperative position and the single shallow furrow cut the first time around the land, and then on the second time around the forward disk may run in the shallow furrow and increase the depth of out. With this arrangement of the disks and the independent manner of mounting them, I am able to cut first a deep, then shallow, furrow, then deep, then shallow, and so on. In case either disk strikes an obstruction in the soil its upward movement to clear the obstruction will be independent entirely of the other disk.
